I know these particular bikes have been talked about a lot. I have searched all over the forums for advice, and reviews. I have narrowed it down to these three bikes. This bike would actually be for my gf, and she has test rode them all. Originally it was only between the Trek and Cannondale, until one of the sales rep suggested she try a marin, plus it was on sale. We are getting into the sport and both don't know much about the particular components that these bikes offer. She is basically going to ride it around town, mostly paved roads. All three bikes are a good fit, they offer there positives and negatives in terms of comfort. We just need a good steer on which direction is the best. Basically we want one that would last, and be the best bang for the buck. The only concern I have is the carbon fiber fork the fairfax and quick 4 offers. I have read on a few opinions on the safety concerns of it shattering. Shes going to take her front wheel off and on quite a bit, and I'm wondering would it cause the carbon fiber fork stress from it at all? Do we have to constantly inspect the fork before every ride? What if she hits a pot hole, does she need to stop and inspect for any cracks? I'm still learning, so these questions may sound silly. Also if anyone has had any prior experience with all 3 which would you choose and why. Thanks in advance.
